The solar aerator device is composed of solar photovoltaic panels, battery packs, aeration systems, and microcomputer control systems. Solar energy is converted into electrical energy through solar photovoltaic panels and stored in batteries as power for aeration facilities. According to the optimized data after debugging, the automatic control is completed through the microcomputer control system, and the aeration facility is run automatically. The water in the river is properly aerated by solar aerator and aerobic biochemical treatment is carried out in the river. In the pool, organic matter is further degraded by microorganisms, and the concentration continues to decrease; The nitrification of ammonia nitrogen significantly reduced the concentration of NH-N, and increased the concentration of NO-N during nitrification; Polyphosphorous bacteria in activated sludge absorb large amounts of phosphorus in sewage under aerobic conditions, convert it into insoluble polyphosphate and store it in vivo. After comparison, the purpose of phosphorus removal is achieved by discharging residual sludge. Solar aerator Zhejiang Jinming Environmental Technology Co., Ltd. was established in March 2010. It is a national high-tech enterprise integrating research and development, production and manufacturing, engineering design, engineering management, EPC project contracting, investment operation and consulting services for environmental engineering and environmental protection equipment. The company has always followed the business philosophy of "scientific and technological innovation" and "management innovation", adhering to the corporate spirit of "seeking truth and innovation, team supremacy, and win-win cooperation" of ZDU, and aims to develop the company into an innovative and leading enterprise in the field of ecological protection. He also established good scientific research and development cooperation with Zhejiang University, Zhejiang Institute of Science and Technology, East China Survey and Design Institute, Zhejiang Academy of Environmental Sciences and other well-known institutions, and relied on its own strong talents and technological advantages to independently develop research and development. Obtain more than 30 items such as new ideas, new technologies, new product invention patents, utility model patents, and software copyright. Since its establishment, the company has been focusing on environmental protection. Its business covers domestic sewage treatment, industrial sewage treatment, river ecological restoration and treatment, rural and industrial sewage maintenance services, industrial dust removal, aquaculture wastewater, medical wastewater, rainwater collection and reuse. To provide pollution control services for industrial construction, building materials, machinery, municipal administration and other industries, has established a lot of project performance throughout the country, won the trust of the majority of customers, has always been "green water Qingshan is Jinshan Yinshan" as the goal of struggle!
